H15EDGKNM-3.5 | 3.5mm Pitch Pluggable PCB Terminal Block Connector

Brand：HOMNECKS

The 3.5mm pitch screwless terminal block (with flange mounting holes on both sides) is a modular terminal block used on printed circuit boards (PCBs). It combines the advantages of quick wiring and mechanical stability.

3.5mm pitch: This refers to the horizontal distance between the center pins of the terminals being 3.5 millimeters. This pitch determines its compatibility with standard 3.5mm grid PCB pads and affects the voltage rating it can withstand (typically used for low to medium voltage applications, such as 300V-600V).

Screwless: This refers to a wiring method using "spring clamp" technology, where wires are secured by pressing a lever or using a screwdriver to operate an internal spring clip, eliminating the need for tightening screws.

Flanged mounting holes on both sides: This refers to the terminal body having protruding "ears" (flanges) on both sides, with through-holes in the flanges. This design is used for additional mechanical fastening of the terminal to the PCB board, securing it with screws or rivets.

Product Overview & Core Design Analysis

This 3.5mm pitch pluggable PCB terminal block connector (H15EDGKNM-3.5) perfectly solves two key industry problems: wiring efficiency and connection reliability.

1. Screwless Wiring Mechanism

Operation: Equipped with an operating lever (push button). Press the lever with a screwdriver or finger to open the internal spring clip, insert the stripped wire, and release the lever for a firm, secure clamp.
Internal Structure: Features a highly elastic, corrosion-resistant copper alloy spring clip (such as phosphor bronze) ensuring constant clamping force, vibration resistance, and anti-loosening properties.

14 pin	15 pin	16 pin	17 pin	18 pin	19 pin
20 pin	21 pin	22 pin	23 pin	24 pin	-

2. Material Of Pluggable Terminal Block

Housing	PA66, UL94V-0
Button	PA66, UL94V-0
Reed	Stainless steel
Contact	Copper alloy, Tin Plated

Key Advantages

Fast Wiring: Wiring speed is several times faster than traditional screw terminals.
Vibration-Resistant: Continuous spring pressure effectively resists loosening caused by vibration, ensuring high reliability.
No Risk of Screw Loosening: Eliminates problems of loose screws or forgotten tightening.
Wire Compatibility: Compatible with crimp terminals, stranded wires, and solid core wires.

3. Electrical Of Pluggable Terminal Block

Rated Voltage	UL: 300V \| IEC: 250V
Rated Current	UL: 8A \| IEC: 7A
Contact Resistance	20mΩ (MAX)
Insulation Resistance	500MΩ / DC500V
Withstanding Voltage	AC 1500V / 1 Min
Wire Range	28-16 AWG

4. Mechanical Of Pluggable Terminal Block

Temp. Range	-40℃ ~ +105℃
MAX Soldering	+250℃, for 5 Sec.
Strip Length	8-9mm

Flange Mounting Holes (Stress Distribution)

Electrical vs. Mechanical Connection: Terminal pins soldered to the PCB handle conductivity, while mechanical stress (pulling, shaking) is transferred via flange mounting screws directly to the robust terminal body, preventing solder joint cracking and PCB copper foil delamination.

9. Terminal Block FAQ

Q1: What key advantages does the slim‑body 3.5 mm KD screw‑free terminal plug offer for compact cabinet designs?

This low‑profile push‑in plug features reduced housing thickness, saving space inside tight control housings and small PLC modules while ensuring quick screwless wiring and vibration resistance.

Q2: What electrical specs and wire range apply to the slim 3.5 mm KD screw‑free plug?

Typical ratings run 300 V, 8-10 A per contact under IEC and UL conditions, designed for 0.5-1.5 mm² solid or stranded conductors (fine stranded wires should use wire ferrules).

Q3: What common wiring errors occur with slim 3.5 mm KD screw‑free terminal plugs?

Common errors include skipping wire ferrules for fine strands, over-inserting bare conductors, and yanking cables forcefully instead of using the built-in release tab.

Q4: Can I pair slim‑body 3.5 mm KD plugs with standard 3.5 mm sockets from other manufacturers?

While 3.5mm pitch keeps physical spacing consistent, slim-version shell contours and spring pressures differ by manufacturer. Always stick to matched sets from one supplier for mass cabinet production.

Q5: What incoming inspection and site commissioning checks are critical for slim 3.5 mm KD screw‑free plugs?

Check release lever feel on incoming batches, verify smooth wire insertion with proper stripping lengths, and give each wire a gentle pull during commissioning to confirm secure spring clamping.
